PURPOSE:To obtain the subject granular material available at a low cost, containing no metal substance by dissolving and isolating heavy metals such as cadmium, excellent in palatability and quality and suitable for feed, etc., of culturing fishes and shellfishes by drying and powdering a solid content obtained by mixing the internal organs of fishes and shellfishes thermally decom posed with a weak acid solution. CONSTITUTION:The objective granular material is obtained by mixing the internal organs of fishes and shellfishes such a scallop with a weak acid solution of acetic acid, etc., and drying and powdering the resultant solid content. |
